While 7kW AC is often too slow for commercial turnover and 120kW DC too expensive for many SMEs, the 15kW EV Charger represents the perfect middle ground. It offers significantly faster "top-up" speeds for destination locations like hotels, shopping malls, and workplaces without requiring the massive electrical infrastructure upgrades of ultra-fast stations.
Current market data suggests a 35% CAGR in the 10kW-22kW power segment. Global enterprises are increasingly procuring 15kW units to future-proof their employee parking and delivery fleets, balancing capital expenditure (CAPEX) with operational efficiency.
Our 15kW solutions are engineered for high-duty cycles. With 23 years of energy expertise, Tongxing ensures every unit maintains a 98.6% field reliability rate through military-grade thermal management and IoT-enabled predictive maintenance.
As a certified national high-tech enterprise, Tongxing New Energy Technology Co., Ltd. has spent over two decades pioneering smart energy solutions. Our 72,000m² intelligent production base in China is the heart of our innovation, achieving a 95% automation rate through 18 automated assembly lines.
140+ certified engineers and 20+ R&D specialists in power electronics and embedded systems ensure cutting-edge hardware-software synergy.
From circuit topology optimization to OCPP 2.0.1 protocol implementation and energy dispatch algorithms, we own 100% of our IP.
IP55/IP65-certified stations designed for performance from -35°C to 75°C, surviving Iceland’s frost and Saudi Arabia’s heat.
12 utility model patents in connectivity and a 78% reduction in standby power consumption over the last 3 years.
Modern commercial districts and logistics hubs require more than just a charger; they need an energy strategy. Our 15kW chargers integrate seamlessly with rooftop solar and LiFePO4 energy storage systems.
| Indicator | Traditional Charging Solution | Tongxing Integrated Solution | Net Improvement |
|---|---|---|---|
| PV Self-Consumption Rate | 50% | 85%+ | ↑ 70% |
| Comprehensive Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓ 27% |
| Annual Carbon Emission Reduction | Baseline | 40% - 60% | Major Impact |
| Grid Response Time | ≤ 50ms | ≤ 10ms | Extreme Stability |
Future 15kW models are being optimized for Vehicle-to-Grid (V2G) capabilities, allowing fleets to serve as mobile batteries for the grid, turning a cost center into a profit center.
While standard for 360kW+ units, we are experimenting with simplified liquid cooling for 15kW-30kW units to extend battery health and maintain peak speeds in tropical climates.
Next-gen firmware utilizes machine learning to predict vehicle arrival times and adjust power distribution across 15kW networks without exceeding site limits.
With strategic partnerships across 45+ countries, we ensure that our wholesale 15kW EV chargers meet and exceed local regulatory requirements, providing peace of mind for international distributors.

A 15kW DC charger bypasses the vehicle's onboard AC-to-DC converter. Many EVs are limited to 7kW or 11kW for AC charging, meaning a 22kW AC charger won't actually charge them faster. A 15kW DC charger delivers the full 15kW directly to the battery, often providing 1.5x to 2x faster results for a wider range of vehicles.
We offer comprehensive White-Label and OEM/ODM services. This includes custom hardware housing colors, logo silk-screening, and localized UI for the touch screen and mobile APP, tailored for your specific brand identity.
Based on our implementations in logistics parks, the average payback period ranges from 3.8 to 5 years, depending on local solar irradiance and grid tariff structures. This ROI is significantly boosted by energy storage peak-shaving benefits.
Yes. All our smart chargers are equipped with Wi-Fi/4G/Ethernet connectivity and support OCPP 1.6J or 2.0.1, allowing for real-time monitoring, remote firmware updates, and billing management via our cloud platform.
Our units feature dual-core redundancy protection, including over-voltage, under-voltage, short-circuit, leakage protection (Type B), surge protection, and emergency stop mechanisms, along with AI temperature monitoring to prevent thermal runaway.
